Abstract
A dehumidifying element includes a dehumidification space that are formed between a pair of potting material portions and that accommodates hollow fiber membranes through which highly humid dehumidification-target air is circulated. The dehumidifying element also includes an air supply hole for supplying purging air having a humidity lower than the dehumidification-target air to the dehumidification space and an air discharge hole for discharging the purging air supplied to the dehumidification space. In the dehumidification space, a guide member is disposed so as to form a plurality of regions in a cylindrical casing as viewed in the axis-L direction, and the hollow fiber membranes are accommodated in the dehumidification space so as to be distributed into the plurality of regions.
Claims9
A dehumidifying element, comprising:
- a hollow cylindrical casing that has casing openings at respective opposite ends thereof in an axial direction of the cylindrical casing;
- a plurality of hollow fiber membranes that are accommodated inside the cylindrical casing in the axial direction for circulating dehumidification-target air;
- a pair of potting material portions that are disposed so as to close casing openings at the respective opposite ends of the cylindrical casing and through which respective ends of the hollow fiber membranes pass;
- a dehumidification space that is formed inside the cylindrical casing between the pair of potting material portions;
- air supply holes for supplying purging air to the dehumidification space;
- and
- air discharge holes for discharging the purging air from the dehumidification space, wherein
- a guide plate that divides the dehumidification space into a plurality of regions around an axis of the cylindrical casing is disposed in the dehumidification space in the cylindrical casing,
- at least one of the air supply holes and at least one of the air discharge holes is formed in each one of the plurality of regions,
- the air supply holes communicate with an annular purging channel surrounding the cylindrical casing, the purging air is supplied to the air supply holes through the purging channel, and
- the plurality of the hollow fiber membranes are accommodated in the dehumidification space so as to be distributed into the plurality of the regions.
